    See all beta I Tubulin primary antibodies
  • Description
    Mouse monoclonal [SAP.4G5] to beta I Tubulin
  • SpecificityNo reactivity with other tubulin isotypes is observed. The antibody is specific for beta I and does not recognize beta II, III, or IV by western blot. Beta VI does contain the sequence. However, there is no experimental proof that the antibody recognizes this isoform.
  • Tested applicationsSuitable for: IHC-P, ELISA, ICC/IF, WBmore details
  • Species reactivity
    Reacts with: Mouse, Rat, Chicken, Hamster, Cow, Dog, Human, Xenopus laevis
  • Immunogen

    Synthetic peptide corresponding to the C-terminal sequence of beta-tubulin isotype I, coupled to BSA.

  • EpitopeAb11312 specifically recognizes an epitope located in the C-terminal sequence of beta tubulin isotype I of human, bovine, dog, hamster, rat, mouse, chicken and Xenopus.

  • Target

    • FunctionTubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha-chain.
    • Involvement in diseaseDefects in TUBB1 are a cause of macrothrombocytopenia autosomal dominant TUBB1-related (MAD-TUBB1) [MIM:613112]. It is a congenital blood disorder characterized by increased platelet size and decreased number of circulating platelets.
    • Sequence similaritiesBelongs to the tubulin family.
    • Post-translational
      Some glutamate residues at the C-terminus are polyglutamylated. This modification occurs exclusively on glutamate residues and results in polyglutamate chains on the gamma-carboxyl group. Also monoglycylated but not polyglycylated due to the absence of functional TTLL10 in human. Monoglycylation is mainly limited to tubulin incorporated into axonemes (cilia and flagella) whereas glutamylation is prevalent in neuronal cells, centrioles, axonemes, and the mitotic spindle. Both modifications can coexist on the same protein on adjacent residues, and lowering glycylation levels increases polyglutamylation, and reciprocally. The precise function of such modifications is still unclear but they regulate the assembly and dynamics of axonemal microtubules.

    • ab11312 (1µg/ml) staining beta 1 tubulin in human placenta using an automated system (DAKO Autostainer Plus). Using this protocol there is strong cytoplasmic staining.
      Sections were rehydrated and antigen retrieved with the Dako 3 in 1 AR buffer EDTA pH 9.0 in a DAKO PT link. Slides were peroxidase blocked in 3% H2O2 in methanol for 10 mins. They were then blocked with Dako Protein block for 10 minutes (containing casein 0.25% in PBS) then incubated with primary antibody for 20 min and detected with Dako Envision Flex amplification kit for 30 minutes. Colorimetric detection was completed with Diaminobenzidine for 5 minutes. Slides were counterstained with Haematoxylin and coverslipped under DePeX. Please note that, for manual staining, optimization of primary antibody concentration and incubation time is recommended. Signal amplification may be required.
